Hi all,

I am working on Sunroof buffeting methodology development and was exploring LES method for correlation purpose using StarCCM+ software.
For LES method, I had studied on full vehicle with around 60 million cells...I am getting good correlation against test in SPL vs frequency output for lower velocities (30kmph to 50 kmph) whereas for higher velocities(>60 kph) the correlation is not good (Peaks not predicted in simulation)

Request if anyone can guide/provide appropriate literature for study to improve correlation at higher speeds.

Any help on this would be highly appreciated.

Thanks and Regards,
Bitty
